Corrections: The animations from 0:14 to 1:03 are used in the cafeteria, I had forgotten about them and remembered now. I'm sorry about that.
Also, the floppy torso animation at 11:00 is used on a hidden jumpscare.

The first part focused on unused animations from Mono, Six and other children, this part focuses on unused animations from monsters.
The most interesting ones can be found on Monster Six's part and The Thin Man's part.

Remember to read the animation names. (They're at the bottom left corner of the screen)
I'm not too fond on what animations are and aren't unused when it comes to some of the monsters, so I may have missed some of them or added ones that are actually used, if that's the case, feel free to correct me in the comment section.
